TGV inOui is the brand name of premium TGV train services operated by SNCF since 27 May 2017 on certain high speed rail services.[1] SNCF is in the process of replacing 'classic' TGV services with the premium inOui and low-cost Ouigo brands in preparation for the future opening of France's high-speed rail infrastructure to competition. The name 'inOui' was adopted because it resembles the French word inouï meaning “extraordinary” (or literally, “unheard of”).[2]
The brand was officially presented in September 2018. Its aim is to replace existing TGV services with "plus de confort, de services et de connectivité" (English: "more comfort, services and connectivity"). In December 2018, trains operated between Lille, Marseille and Nice from Paris and operated on the rest of the network from 2020.[4]
